Renders GeoJSON tiles on an L.GeoJSON layer.
Docs
Usage example
The following example shows how to render a GeoJSON Tile Layer for a tile endpoint at http://tile.example.com/{z}/{x}/{y}.json.
var style = {
"clickable": true,
"color": "#00D",
"fillColor": "#00D",
"weight": 1.0,
"opacity": 0.3,
"fillOpacity": 0.2
};
var hoverStyle = {
"fillOpacity": 0.5
};
var geojsonURL = 'http://tile.example.com/{z}/{x}/{y}.json';
var geojsonTileLayer = new L.TileLayer.GeoJSON(geojsonURL, {
clipTiles: true,
unique: function (feature) {
return feature.id;
}
}, {
style: style,
onEachFeature: function (feature, layer) {
if (feature.properties) {
var popupString = '<div class="popup">';
for (var k in feature.properties) {
var v = feature.properties[k];
popupString += k + ': ' + v + '<br />';
}
popupString += '</div>';
layer.bindPopup(popupString);
}
if (!(layer instanceof L.Point)) {
layer.on('mouseover', function () {
layer.setStyle(hoverStyle);
});
layer.on('mouseout', function () {
layer.setStyle(style);
});
}
}
}
);
map.addLayer(geojsonTileLayer);
Constructor
L.TileLayer.GeoJSON( <String> urlTemplate, <GeoJSONTileLayer options> options?, <GeoJSON options> geojsonOptions? )
URL Template
A string of the following form, that returns valid GeoJSON.
'http://{s}.somedomain.com/blabla/{z}/{x}/{y}.json'
GeoJSONTileLayer options
clipTiles (boolean) (default = false): Iftrue, clips tile feature geometries to their tile boundaries using SVG clipping.unique (function): If set, the feature's are grouped into GeometryCollection GeoJSON objects. Each group is defined by the key returned by this function, with the feature object as the first argument.
